Galaxy Note 10.1: Not charging?

I got my Note 10.1 yesterday. I immediately hooked up the USB cable to a port on my computer and left it for a while to charge. Based on the flashing icon on the screen, I believe that was working just fine. It came out of the box with what looked like around a 60% charge. It charged for a about 2 hours then I took it off, fired it up, and started playing with it. It was not at 100% charge, but it was pretty high.

This morning, I hooked it back to the same USB cable connected to my computer. The battery now shows 76% charge and it has a red X on it and the battery status is discharging. I.e. under Settings / Battery, it says "76% - Discharging".

Why is it not charging now, when I have it hooked to my PC?

I rebooted it and it came back up the same. My computer shows that it's connected. The Note status bar has the USB symbol and says it is connected as a media device.

Re: Not charging?

Mine charges very slowly when connected to anything but the stock A/C brick, including my BlueLounge Refresh. My guess - the stock A/C brick delivers a higher than standard power output, much like the Nexus 7 A/C brick.

Re: Not charging?

You will not be able to use the USB cable supplied to charge the Tablet via computer with the tablet on. If you have the tablet on with the cable plugged into the computer, you will see a red X over the battery icon on the tablet. This means the battery will only drain but not enough power from computer to charge the tablet and use it at the same time. U can only charge the tablet plugged into the wall with the supplied adapter.

Not charging?

A PC USB port has a maximum current of 0.5 amps available, sometimes even that small amount is shared with an adjacent USB port. This is plenty for keyboards and pen drives etc, but not enough to charge a phone or tablet.

To recharge the 7000mAh battery in your Note at 0.5 amps would take at least 14 hours even if the tablet was switched off. I think the supplied charger is a 1 amp device.

Re: Not charging?

Being that the supplied cord is worthless being to short, I have the usb adapter, tried to plug a 6' usb to usb cord into the block and can't get it to charge.is there a setting I am missing? Or are we just stuck by Samsung on using this stupid cord

Re: Not charging?

It is a similar issue as mentioned before. The power block that came with the tablet is 2.0 amps. The cable that comes with the tablet is probably long enough to allow the 2 amp charge.

A usb extension cable could lessen the charge, or be missing a pin altogether. It is no different than using an extension cord on a power hungry appliance. Unless you up the gauge of the wire in the extension cord, basic electrical resistance will lessen the operating voltage getting to the appliance. 6 feet may not seem like a lot, but when the wire is #24 or smaller, it doesn't give the ability to keep the proper amperage at the tip.

Another thing is that i have heard that samsung's usb cables may have a slightly different pin configuration, which would be weird, as there are only 4 contacts in a usb tip.

I think your problem is your USB adapter. If it's the adapter for letting you connect, say, an external hard drive, I suspect it just doesn't allow charging through that adapter. I bought a longer cable that has the Samsung dock connector on one end and it works fine.

Re: Not charging?

When I got a charger with my case it said 2.1a output. It's not a Samsung charger but it does charge just as fast as the Samsung one. I tried another one, a Hyperon battery/usb plug in charger with a usb port and the original Samsung usb to 30 pin connection cable and it will show the little red line across the battery icon but it will still trickle charge but it's VERY slow. I've misplaced my original Samsung one and have been looking at chargers and external battery packs. There are a lot of chargers out there on Amazon and such that say it'll work with the Note 10.1 but it's only 1.0a output. I'd stay clear of those and look for the 2.1a chargers.

Re: Not charging?

I believe this is to protect your USB from frying. USB ports usually run at 5 Volts but can give 0.5 Amps if I am not mistaken. The Galaxy needs a 2.0 A current, and if it tries to get this from your USB, it will probably cause damage to it. So this is a smart move to avoid burning it. The 0.5 A will be enough to run through your Galaxy as a USB drive to read your files.

Re: Not charging?

There is lots of misdirection here. It isn't about cables or protecting ports or the size of battery or keeping the battery at full charge (a complete falsehood).

It is amperage. As has already been said, the tablet, like many phones these days, needs at least 2 amps to charge at the rate you are familiar with--or a reasonable rate. Your normal USB port doesn't get close to that many amps, which means painfully slow charge if at all. Lots of folks buy these generic charging adaptors and Car lighter adaptors with USB ports without checking for their output, and then they complain about the charging rate.

Well said.

For those that want a longer charge cable dont extended the usb lead
A simple solution is to change the adapter that plugs into the mains with a standard mains lead the type that found on say an old portable tape deck or the type used on the new shape ps3

Re: Not charging?

I have a samsung galaxy 7.0 and whenever I charge it an x goes over the charging bar. Why is that? I plugged it intp the wall but it seems to not work. If I plug it, then it says 100% but it decreses in charge rapidly. It only seems to charge when I turn it off, but this only charges all the way sometimes. Please help.

Re: Not charging?

Hi i am having the same problem with my note but it has been charging fine up till now. Ive had it since christmas. Although i dont connect it to a computer just a normal ac power supply. Now, when i plug it in the battery power is going down instead of up. I left it on charge for most of last night nd it still went down from about 20% to 4%. It was turned off. I really need someone to help please.

Re: Not charging?

Re: Galaxy Note 10.1: Not charging?

I have experienced the same problem as the rest of you.
The suggestion of changing around the pins of the brick adapter
into the power socket worked for me, fully charged in about two hours!
Thank you whoever made the suggestion.

Re: Galaxy Note 10.1: Not charging?

IF USB cord is to short, put the "wall wart" (charger block) on extension cord.... Using PC and USB cord does not work, PERIOD... Its the amperage thing as others have said.... Charger needs to be 2+amp (2100ma) ...

Though I do have heavy duty USB extension cord (3 ft - off some device discarded a long time ago) that extends USB side of charger and it works fine...
